HENRY HIGGIN, or NEWPoRnKENTucKY, Assienon or ONE-HALF TO THE I-IIGGIN.

MANUFACTURING COMPANY, OF.1\TEWPORT,;KENTUCKY, A CORPORATION OFVIRGINIA.

To all whom it may concern: Be it 'known' that I, HENRY HIGerN, acitizen of the United States,and a resident of the city of Newport, inthe county of- Campbell and State of Kentucky, have invented certain newand useful Improvements in Window-Ventilators, of which the therebyadmitting an indirect current of air into the room. I It has 'special'relation to window ventilators of the kind shown and described in myLetters Patent No.1",O64,"7 30,

issued June 17, 1913. 1

The object of the invention is to provide an effective means ofadjustably mounting such a ventilator in windows-so as to accommodatethe variations of size in the frames of windows, and this without in anyway interfering with theuse of the ventilator, or leaving gaps betweenits sides and the window frames. l

It has been the subject of much investigation and trial to devise amounting means to answer this purpose. In the patent referred to, whilethe mounting is adjustable to a certain degree, there is only latitudefor slight adjustment, and it can be appreciated that such a windowventilator for a window of certain general size would be rendereduseless if because of the usual variation of the size of that windowfrom the normal it could not be used.

I accomplish the purpose mentioned and certain other advantages whichwill be de scribed by that certain construction and arrangement of partsto be hereinafter more specifically pointed out and claimed.

In the drawings, Figure 1 is an elevation of the ventilator and windowtaken from the outside, in raised position. Fig. 2 is a perspective viewof one end of the ventilator in place, taken from the outside. Fig. 3 isa perspective view of the end wall and attaching means, being the onesshown in Fig. 2, but removed from the window and turned half way around.Fig. 4 is a vertical sec tion taken just inside of the end wall show-Application filed April 16, 1914.

ing the ventilator screen being removed fori cleaning. a

. The window isof the ordinary type, having-a silll, a sliding sash witha lower rail 2, and a bead 3 upon which the sash slides: "The ventilatorcomprises a boxlike. structure, having a bottom portion 4 and end walls5. The end walls have inwardly extending flanges 6, 7, 8 and 9.

A pivoted side wall 10, having knobs 11,

for opening and closing the same is mounted within the box by means of acurved flange 12,:inserted under the bead 13formed in the bottom portion4. The topjedge of the wall 10 is provided with a bead 14,

which fits into a bead 15 formed atthe meet ingpointof the flangesfl and7 of the end walls." This'structure provides aweathertight fit of theinner wall, and a means for holding the wall in its raised or closedposition. For further details as to this construction, reference is madeto the Letters Patent above mentioned.

The flanges 9 of the end pieces and the flanges-6 are cut away at 16 toleave an opening for inserting and withdrawing the screen 17 fromtheventilator; The screen is formed of a perforated plate of the sizeof-the' box, having wire gauze secured to it if desired, and hooks 4:7for connecting it to the lower window sash.

In securing the box to the window, the bottom flanges 8 and the bottompieces l are screwed to the window frame after the box is locatedinposition. l 9

-Riveted or otherwise secured on the outer face of the end pieces arethe angle plates 18. These plates have their upper edge 19 preferably ona level with the top flange of the end plates 5 and extending on acontinuation of the plane of the flange 9 of the plates 5. They have,also, an inturned base flange 20 provided with a hole 21 for screwingthem to the sill when properly positioned.

Angle plates 22 are provided for the purposes of mounting the ventilatorbox. These plates at their upper end have loops or turned flanges 23 toslide on the edges 19 of the plates 18. The inturned portions 24 of theplate 22 are adapted to be inserted under the head 3 and screwed intoplace there (Fig. 2), or else countersunk into the face of the bead inthe ordinary manner.

The laterally extending portions of the width of the plates along thetop edge Now since the plate 22 will slide on the plate 18, and sincethe flange extends the whole'width of the plate 22, the latitude foradjustment without leaving any opening between the 'end plates and thewindow frame is equal to substantially the entire width of the plate22.-, 5 Q 3,

The manner of mounting the ventilator box is to place it 'in the desiredposition and then slide the plates 22onto the edge ofvthe brought downover them. Then the other bottom portions, asheretofore mentioned,-

are screwed into place. 7 7

It can now be seen that the adjustment of the mounting plates 22jiseasyand of sufiicient magnitude. The parts should not be mounted so thatthese plates interfere with the removing of the screen .(Fig. 4) throughthe" flange openings at 16. If desired, the new mounting. may-be usedvonone side only and-the end plate 5 at the other end screwed directly ontothe window frame,fas at the left side of Fig. l'of the drawings. w :Tohave a flange or-loop similar to th loop .23 on the end platesthemselves is not satisfactory, because to have any latitude foradjustment wouldrequiresuch an extension from the end plates as torender the ventilator so 3 equipped useless in any but abnormalsituations because of being too lc-ng to fit. This difliculty isovercome by my structure V V Another advantage is that the loops 23 asshown in this. improved mount-ing give an additional support to theventilator box. It is at theattachment side of the box that the windowslides and such strain as is placed' plates 18. The portions 24 of theformer plates are then screwed in place and the bead onf the boxapplieddirectly at the point where the window brings the ends of thescreen 17 into contact with the flanges of the end pieces. If then theloops were on the end plates, none of the strain would be taken by theplates 22, which on the con- "jtrary would remain in place even if theen tire box were torn away.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is

1. In a device of the character described, a ventilator box member, andmeans for securing the same in the frame of a window, comprising a platesecured to the said box member, said plate having a laterally extendingportion for securing it to the box member, a base portion for securingit to the-window sill, and a vertical portion extending parallel withsaid sill, and a plate having a vertical member provided with means forslidably engaging the vertical member of the plate first mentioned, anda lateral member for securing it to the side of the window frame. 7

2. In a device of the character described, a ventilator box member, andmeans for securing the same in the frame of a window,

comprising a plate secured to the said box member, said plate havinga'laterally extending portion for securing it to the box member, a baseportion for securing it to the window sill, and a vertical portionextending parallel with said sill, and a plate having a vertical memberprovided with a downwardly depending flange for slidably engaging thevertical member of the plate first mentioned, and a lateral member forsecuring it to the side of the window frame.
